C. rigidulus and discover what makes it so fascinating.

Background on Mosses

Mosses are non-vascular plants in the division Marchantiophyta. Unlike other land plants, they lack true roots, stems, and leaves. Instead, they have leaf-like structures called phyllids. Mosses reproduce via spores rather than seeds and are found in diverse habitats worldwide, from arctic tundra to tropical rainforests. There are over 12,000 moss species.

Morphology and Identification

Chiloscyphus rigidulus

is a leafy liverwort, meaning it has two rows of phyllids arranged on either side of the stem. The phyllids are oblong to oblong-ovate in shape, with entire margins. The underleaves (modified phyllids on the underside of the stem) are much smaller than the lateral leaves. C. rigidulus forms loose mats on its substrate. It is dioicous

, with separate male and female plants.

Global Distribution and Habitat

C. rigidulus has a wide distribution

, found in Europe, Asia, Africa, and the Americas. It grows in moist, shaded environments such as on soil, rocks, tree bases and rotten logs in forests. This species prefers

acidic substrates.

Ecological Roles and Adaptations

Like other mosses, C. rigidulus plays important roles in its ecosystem:

  • Helps retain moisture and prevent erosion
  • Provides shelter and food for micro-organisms and insects
  • Pioneers the colonization of bare ground
  • Indicator of air and water quality

C. rigidulus has several adaptations that allow it to thrive:

  • Poikilohydry – can survive desiccation by suspending metabolic activity when water is scarce
  • Absorbs water and nutrients over its entire surface
  • Reproduces asexually via fragmentation


Chiloscyphus rigidulus may be small, but it is a resilient and ecologically important moss species. Its ability to grow in diverse habitats worldwide and its role in supporting other organisms make it a fascinating plant to study. Next time you’re in the woods, take a closer look – you just might spot this mighty moss! What other amazing bryophytes have you encountered?
